RAMI254EXT-LB5
Ground Based Communications | Tri-Band
The RAMI254EXT-LB5 is a replacement for the OE-254/GRC Antenna Group. It is comprised of fewer piece parts, allowing for quicker assembly and erection, along with being capable of VHF, UHF and L-Band operation modes. It can be deployed atop its 27 ft. mast (RAMI5008-FG) or utilized on the ground standing on its tripod base. It is manufactured to meet the mechanical and environmental specifications as called out in MIL-PRF-49204 (OE-254/GRC specification). The antenna comes complete with a 100 ft. LMR-400 transmission line with an in-line adapter (antenna to triplexer) and three 5 ft. RG-223 transmission lines (triplexer to radio set). Additional components for full assembly and erection (mast to ground deployment) are sold separately.
